Correlative microscopy approaches offer synergistic solutions to many research problems. One such combination, that has been studied in limited detail, is the use of atom probe tomography (APT) and transmission Kikuchi diffraction (TKD) on the same tip specimen. By combining these two powerful microscopy techniques, the microstructure of important engineering alloys can be studied in greater detail. For the first time, the accuracy of crystallographic measurements made using APT will be independently verified using TKD...

At the beginning of the twentieth century, the hypothalamus was known merely as an anatomical region of the brain lying beneath the thalamus. An increasing number of clinicopathological reports had shown the association of diabetes insipidus and adiposogenital dystrophy (Babinski-Fröhlich's syndrome), with pituitary tumors involving the infundibulum and tuber cinereum, two structures of the basal hypothalamus. The French physicians Jean Camus (1872-1924) and Gustave Roussy (1874-1948) were the first authors to undertake systematic, controlled observations of the effects of localized injuries to the basal hypothalamus in dogs and cats by pricking the infundibulo-tuberal region (ITR) with a heated needle...

BACKGROUND: Arnold-Chiari malformation Type 1 (ACM-1) in parturients is a topic of ongoing discussion between obstetricians and anesthesiologists. The primary unanswered question remains; How should the anesthesia provider proceed with labor analgesia and anesthesia for cesarean section when confronted with an advanced, asymptomatic, or minimally symptomatic case of ACM-1 during labor? CASE DESCRIPTION: A 24-year-old, ASA II, G1P0 full-term parturient presented to Labor and Delivery for vaginal delivery...

Heterozygous germline gain-of-function mutations of G-protein subunit α11 (Gα11), a signaling partner for the calcium-sensing receptor (CaSR), result in autosomal dominant hypocalcemia type 2 (ADH2). ADH2 may cause symptomatic hypocalcemia with low circulating parathyroid hormone (PTH) concentrations. Effective therapies for ADH2 are currently not available, and a mouse model for ADH2 would help in assessment of potential therapies. We hypothesized that a previously reported dark skin mouse mutant (Dsk7) - which has a germline hypermorphic Gα11 mutation, Ile62Val - may be a model for ADH2 and allow evaluation of calcilytics, which are CaSR negative allosteric modulators, as a targeted therapy for this disorder...

Transmission electron backscatter diffraction (t-EBSD) has become a routine technique for crystal orientation mapping when ultrahigh resolution is needed and has demonstrated advantages in the characterization of nanoscale and micron-sized samples (Babinsky et al., 2015). In this work, we use experimental measurements and simulations to compare the resolution of the transmission and conventional reflection EBSD techniques across a range of sample volumes and characterization conditions. Monte Carlo simulations of electron trajectories provide the opportunity to estimate beam size and effective resolution, as well as electron flux, as a function of sample thickness or incident beam energy in t-EBSD...

Hashimoto's Encephalopathy (HE) is a rare form of autoimmune encephalopathy associated with Hashimoto's thyroiditis in which patients experience cognitive impairment and various neurologic symptoms. We present a case of a young female that presented to the emergency department with urinary retention, and was ultimately diagnosed with HE. Examination was significant for direction-changing and vertical nystagmus (direction-changing nystagmus describes a phenomenon where the fast beat changes with the direction of gaze), hyperreflexia, clonus, and Babinski and Hoffman's reflexes (all upper motor neuron (UMN) signs)...

Biobanks are resources that facilitate research. Many biobanks exist around the world, but most tend to focus on a specific disease or research area. BC Children's Hospital and BC Women's Hospital are located on the same campus (Oak Street Campus) in Vancouver, BC, Canada. A campus-wide biobank has been established on the site of these two hospitals to collect specimens and annotated data from children or women seeking medical care at either of the hospitals. Such an initiative requires careful planning and consideration of many factors such as buy in and support of key stakeholders, governance, financial planning, and optimizing specimen collection...

Craniopharyngiomas (CPs) are benign epithelial tumors that develop along the hypothalamus-hypophyseal axis and were first described by Jakob Erdheim in 1904. These tumors have represented a challenge for surgeons since the rise of modern neurosurgery. The study of CPs is linked to the development of this surgical discipline in parallel with neuroendocrinology within the French school of neurology, led by Joseph Babinski. For the present study, all CP cases published in the French scientific literature before the development of modern neuroradiology were gathered, and 65 cases that underwent surgical procedures between 1921 and 1973 were selected...

BACKGROUND AND IMPORTANCE: Amputation neuromas consist of non-neoplastic collections of myelinated axons and Schwann cells and typically arise in injured peripheral nerves. Rarely, however, neuromas occur within the spinal cord. Intramedullary amputation neuromas have been described both with and without a history of trauma within the peripheral nervous system. We report a rare case of an isolated intramedullary spinal cord amputation neuroma. CLINICAL PRESENTATION: This 43-year-old man presented with progressive and severe gait deterioration for ~ 7 years...

BACKGROUND: Ossification of the posterior longitudinal ligament (OPLL) can cause myelopathy that is often managed surgically. Knowledge of predictors of surgical outcomes can provide decision support to surgeons. The aims of this study were to investigate the relationships between preoperative physical signs and postoperative functional outcomes in patients with OPLL and to clarify whether physical signs could predict functional outcomes. METHODS: Fifty-five patients with OPLL who had undergone cervical laminoplasty were included in this study...

Hemifacial spasm (HFS) is one of the most common presentations in patients with cranial psychogenic (functional) movement disorders (PMD). Medical records and videos of patients with PMD and HFS were reviewed to identify those with psychogenic HFS and to compare the phenomenology of psychogenic HFS with organic HFS. We identified 18 (9.8%) patients with psychogenic HFS from a cohort of 184 patients with PMDs. There were 14 (78%) women and 4 men, with a mean age at onset of 33 ± 13.5 years. These were compared with 37 consecutive patients with organic (primary) HFS...

Liquefied hydrocarbon gas, such as propane is considered safe. However there are reports that voluntary exposure to liquefied gas at least could originate hallucinatory states. We report a 20 years old woman who was found in a coma with extensor muscle hypertonia, brisk tendon reflexes and extensor plantar (Babinski) responses after being exposed to propane gas. The brain magnetic resonance imaging (MRI) showed lesions in both hippocampi and white matter in the oval center. The patient had a normal oxygen saturation of 98%, a carboxyhemoglobin of 1...

BACKGROUND: Rapid-onset dystonia-parkinsonism (RDP) is a rare autosomal dominant disorder that is caused by mutations in the ATP1A3 gene and is characterized by an acute onset of asymmetric dystonia and parkinsonism. To date, fewer than 75 RDP cases have been reported worldwide. Clinical signs of pyramidal tract involvement have been reported in several RDP cases, and none of them included the Babinski sign. CASE PRESENTATION: We report a 24-year-old Chinese female with RDP who exhibited a strikingly asymmetric, predominantly dystonic movement disorder with a rostrocaudal gradient of involvement and parkinsonism...

The Babinski Sign is one of the most clinically relevant diagnostic signs in medicine. Though the plantar reflex is practiced thousands of times across the globe every day, few realize its historical importance. In this narrative review we trace the origins of the Plantar Reflex back in the 19th century, discuss its evolution over time and examine the body of evidence behind the current understanding. State of the art diagnostic modalities like video analysis and electromyography have helped us in dissecting the pathophysiology behind the simple yet beautiful Babinski Sign...

BACKGROUND Despite being the most common tumor of the spine, vertebral hemangioma is rarely symptomatic in adults. In fact, only 0.9-1.2% of all vertebral hemangiomas may be symptomatic. When hemangiomas occur in the thoracic vertebrae, they are more likely to be symptomatic due to the narrow vertebral canal dimensions that mandate more aggressive management prior to the onset of severe neurological sequelae. CASE REPORT An 18-year-old male presented to the emergency room with a one-month history of mild to moderate mid-thoracic back pain, radiating to both lower limbs...
